A Bi-Directional Dual-Input Dual-Output Converter for Voltage Balancer in Bipolar DC Microgrid
Energies, 2022 Bipolar DC microgrids (BDCMGs) have several issues related to the voltage and require numerous converters to supply power to both poles. To solve these issues, a bidirectional dual-input dual-output (DIDO) converter is proposed for the voltage balancer ...

A Half-Bridge Voltage Balancer with New Controller for Bipolar DC Distribution Systems
Energies, 2016 This paper proposes a half-bridge voltage balancer with a new controller for bipolar DC distribution systems. The proposed control scheme consists of two cascaded Proportional Integral (PI) controls rather than one PI control for balancing the pole ...

Control Strategy in DC Microgrid for Integrated Energy Balancer: Photovoltaic Application [PDF]
Iranica Journal of Energy and Environment, 2022 Renewable energy is energy that can be used indefinitely. As a result, renewable energy sources such as solar photovoltaics developed. Conventional converters, typically used to connect the microgrid to the battery, only change the voltage.

An AC Voltage Balancer and its Improved Modulation Strategy for CHB Based PV Inverters
IEEE Open Journal of Power Electronics, 2023 Cascaded H-bridge (CHB) inverters have been widely used in distributed photovoltaic (PV) power generation systems due to their attractive features in terms of power quality and easy to expand compared to two-level or three-level inverters. Especially the

Double integral sliding mode control of a Buck-Boost voltage balancer
Dianzi Jishu Yingyong, 2018 The bipolar DC micro-grid based on the Buck-Boost voltage balancer framework has been widely studied. The effective control voltage balancer keeps the positive and negative voltage of the system equal, to ensure the power quality of the system. Aiming at
